We moved into an early seventies suburban above ground ranch style home. The town is mostly underground wiring. Before I had done anything I was auditioning the PS Audio HCA-2 class D switching amplifier. The clock radio in the bedroom was picking up interference from the audio system.
Having the mains service increased came with all new cable from the utility source. Code required losing the aluminum wire between the utility breaker and the homes panel.
From there I had a dedicated sub panel that fed both the two channel and HT systems. The runs were 10 gauge metal clad BX terminated with isolated ground (orange) receptacles.
For less than $800 the results were stunning.
